【摘要】JavaScript传统上是单线程的，在HTML页面中执行一个需较长时间运行的脚本会阻塞所有的页面功能直至脚本完成。Web Worker是HTML5提供的JavaScript多线程解决方案。解析了Web Worker的工作原理和过程；提供了Web Worker代码示例和代码调试方法；说明了使用 Web Worker如何提高 Web应用的性能。由于 Web Worker相对较新，目前关于Web Worker的示例和文献非常有限。该研究院提供了Web Worker的参考应用场景及进一步研究和应用的方向。%JavaScript is traditionally single-threaded ,execute a script that takes a long time to run in an HTML page ,all pages function will block until the script is completed .Web worker is a multi-threading solution JavaScript HTML5 pro-vides .Parses the working principle and process of web worker ,provides web worker code examples and code debugging methods ,and explains how to use the web worker to improve the performance of web applications .As the web worker is relatively new ,currently the examples and literature on the web worker is very limited .Provides a reference application scenarios of web worker and the direction of further research and application .
